American Airlines flight attendants are outraged over a company-wide competition to find the best-looking female and male air stewards at each crew base. The winners are to model the airline's newest uniforms in marketing material, but the flight attendants' union won't have it. Laura Gladling, president of the Association of Professional Flight Attendants, emailed the union's 18,000 members today calling for an end to the "ridiculous, insulting beauty contest", according to Bloomberg. Gladling said that the model search undermines the flight attendants' primary duty: in-flight safety.

The "Face of Your Base" campaign only started this week, but it's already causing its fair share of controversy. While many won't want to be involved in the contest, some flight attendants are "flattered", according to Missy Cousino, a spokeswoman for the AA base of Fort Worth, Texas. Airlines have a long history with glamourising the air host/hostess profession. From the early days of Pan Am, soon to be turned into a Mad Men-style TV show, to over-the-top sleazy commercials like a regional Russian airline's bikini-clad hosties washing an aeroplane, to annual surveys revealing the world's top 10 sexiest airlines, there are countless examples of where the airline industry focuses on its employees' 'assets'. And we're not talking cart-pushing, people... Is the campaign outdated or just a bit of fun? Share your thoughts below. PHOTO GALLERY: Mexican air hosties star in Playboy
